The fling works nicely on W2K8. Now I’m trying to get back free space from Linux VMs and I thought using vHardware 9 + ext4 with discard mount option should achieve the same but it’s not working. Kernel 3.2.x, wrote some data on the filesystem with discard option, deletet it, wrote zeroes with dd, removed the zero file. The VMDK file does not shrink.
Any idea what I’ve to do on Linux?
